EROSION PREVENTIVE SOIL TILLAGE TOOL Russian patent published in 2003 - IPC

FIELD: agricultural engineering. SUBSTANCE: tillage tool has frame with bar positioned at an angle to longitudinal axis. Plow bodies with plow-bottom surfaces and disk battery are fixed to bar. Disk battery has carrier member positioned at an angle to longitudinal axis of tillage tool and equipped with disk-type working tools. Disk-type working tools are mounted on carrier member by means of brackets. Terminating plow body is defined by ripper-plow body made in the form of tine curved at an angle of 45 deg to horizontal plane and chisel positioned on tine lower part. Tine on frame bar is offset by 1/2-1/4 the width of front plow body with plow-bottom surface. Spherical disk is mounted in front of each of said bodies on carrier member by means of brackets at an angle to advancement direction and projection extending toward body tine. Additional spherical disk is mounted in ripper-plow tine clearance on frame so that it faces with its concavity toward terminating tine of plow body with plow-bottom surface. EFFECT: increased efficiency and provision for keeping increased fertility of soil on eroded sites. 2 dwg
